    摘要:

    我国是世界上草莓属植物的主要分布区之一,具有丰富独特的野生种质资源。遗传资源的有效利用是草莓种质创新和产业发展的重要推动力。为了厘清我国野生草莓种质资源的种类和分布规律,从2016-2023年历时8年时间对我国的草莓野生资源进行了调查收集研究。共在云南、黑龙江、湖北等10个省、市、自治区26个县域收集草莓野生资源172份。根据生物学性状,可归类为8个草莓野生种,其中五叶草莓(F. pentaphylla)60份、黄毛草莓(F. nilgerrensis)42份、西南草莓(F. moupinensis)29份、森林草莓(F. vesca)8份、东方草莓(F. orientalis)5份、东北草莓(F. mandschurica)15份、中国草莓(F. chinensis)10份、伞房草莓(F. corymbosa)3份。总体的分布情况可划分为四个区域,西部地区主要分布五叶草莓、黄毛草莓、西南草莓和中国草莓4个种,华中地区主要分布黄毛草莓和中国草莓,华北地区主要分布伞房草莓,东北地区主要分布森林草莓、东方草莓、东北草莓3个种。同时,通过考察获得了特异的草莓野生资源,如粉果类型的五叶草莓,极芳香的黄毛草莓,果实风味好的东方草莓等。这些结果让我们对我国的草莓野生种质资源有了更加深刻的认识,也将为资源的保护、利用和科学研究提供有力的参考。

    Abstract:

    China is one of the main distribution areas of the genus Fragaria with typical and unique wild germplasm resources. The utilization of these genetic resources will play an important role in germplasm innovation and industry development in strawberry. To figure out the taxonomy and distribution patten of the wild strawberry species in China, we conducted the investigation and collection research over a period of 8 years, from 2016 to 2023. A total of 172 wild strawberry accessions were collected from 26 counties of 10 provinces including Yunnan, Hubei and Heilongjiang etc. According to their biological characteristics, the 172 accessions were classified into 8 species: F. pentaphylla (60 accessions), F. nilgerrensis (42 accessions), F. moupinensis (29 accessions), F. vesca (8 accessions), F. orientalis (5 accessions), F. mandschurica (15 accessions), F. chinensis (10 accessions), and F. corymbosa (3 accessions). The overall distribution could be divided into four major regions, the western China mainly distributed four wild species including F. pentaphylla, F. nilgerrensis, F. moupinensis and F. chinensis; the central China mainly distributed F. nilgerrensis and F. chinensis; the northern China distributed F. corymbosa; and the northeastern China mainly distributed three species such as F. vesca, F. orientalis and F. mandschurica. Also some specific wild resources were identified in our investigation, like F. pentaphylla with pink fruits; F. nilgerrensis with aromatic fruits; and F. orientalis with good flavor fruits; etc. These findings given us a more impressive understanding of the wild strawberry germplasm resources, and provided valuable references for the conservation, utilization and scientific research of the resources.
